During an In process inspection of supplier the third party inspector found the supplier using ER70S-6 instead of the WPS specified ER70S-2 filler metal. The supplier agreed to remove the S-6 and reweld with the required S-2. My question is will this be justified NCR on supplier? I know the S2 and S6 have the same F# and SFA # tensil stregth is like 10k difference and then you have the fact of re welding.

Similarly E71T-1 and some other classifications within SFA 5.20 for flux core can exceed the limit for Mn imposed by QW 442 for A1, but we use tons of it every year and always get material that meets A1.
RE: WPS
Our procedures must be aproved by TSSA and as far as I know they have always taken the stace that because the consumable can exceed the limits imposed by SFA 5.18 the wire is not aproved. Do you specify in your procedure that the MTR for filler metal is inspected and aproved before use?

I'm in Texas and have not dealt with TSSA but I have submitted WPS' to other jurisdictions in Canada without issues.
